other substances, and thereby expose a free metallic surface to theaction of agencies for the reduction of baser metals. I also create apressure causing the gases-to penetratemore thoroughlyt-hesubstances-tobeoperatcd upon, prevent the escape of matter by blastior draft,

1 either by precipitating or holding them in solution.

To enable others to make and use inyinventiou, I will proceed todescribe it by reference to the accompanying drawings. The same lettersrefer to the same parts.

Figure 1 represents a longitudinal section of the apparatus. Fig.2represents a transverse section of it; and Fig; 3 represents an endelevation.

There is adrmn, A, Figs. 1 and"2, revolvin g slowly within afurnace, B,having a connection with hopper G for the admittance of pulverized oreand an aperture, F, for the removing of the desulphurized anddisintegrated metal. There is a. tube, E, perforated on the under sideas far as it reaches into the revolving cylinder A, forthe introductionof the com pressed air or other gases, and-a tube, D, hav- 3 ingitsinlet near the'highest elevation of cylinder A, for the escape of the:gases into the next vessel. Anumber o'f balls,G G GG G G,

&c., roll within the said cylinder A. Tube D, with cockj M, leads to aclosed vessel or seal, H, Fig.1,saidvesse1beingpartially filled withwater, acid, or alkaline solution. The outlet of tube D has-to be belowthe surface of the above mentioned fluid, and near the bottom of theseal. Another tube, D, is leading from seal H to a similar one, H, andin like manner another tube, D, to seal H", and so on until tube D"terminatesin box Lwhichis partitioned ofi, as shown in Fig. 1, havingthe last partition dip into a vessel, K, filled with mercury. I From thelast space a pipe, L, carries all obnoxious gases off or into a chimney.it The apparatus has to he used in the following manner: A quantity ofpulverized ore being placed through hopper 0 into a slowly-re volvin gcylinder, A, and there exposed to the action of heat from furnace B,,the balls GG .G G, &c.. distribute the metallic ore more uniforr'nly,and by their constant friction against the ore remove-all coating ofoxide or other substances, and cause it to present a bright metallicsurface to the action of the agents used for the reduction of the-beset-metals.

The tube E introducesa blast of compressed air or gases into thecylinder, which, acting upon the ore, assist the process-ofdesulphurizing, and carries off the freed gases into the "seals H H H"H'", &c., and box I, where they become condensed, according to theirnature,

and are precipitated or held in solution, as

mentioned above. Theseals H H H", 800., also arrest the escapeotm-atter, so that there.-

is no lossof the yaluable metallic ore.

By opening theco'ck M, I am enabled-to test the nature ofthegases in thecylinder, and

after the same are allcondensed the desulphurized ore is then taken fromaperture F.

p In this apparatus I do not confine myself to the number of seals H HH" H', 850. This.

depends on the substance tobe operated upon.

What 1 claim as my invention, and desirto secure by LettersPatent, is--t The revolving cylinder A, incombination with balls G G G", &c., ortheir equivalents, tubes E and D, cock M, and seals HH H"; &c.,constructed in the man purpose above described. l

I In witness whereof I have hereunto subscribed my name the 10th day. ofMay, 1865.
